Could you send the log returned by:

  guix build --log-file /gnu/store/brvizic3qv469j8fd2xgsgx9p8s5s1j7-google-brotli-1.0.7-checkout

?

It looks like the download code provided invalid data, which led (guix
status) to pass transferred = #false to ‘display-download-progress’.  I
can’t reproduce it, though.

Thanks,
Ludo’.
